What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock held at a height has gravitational potential energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What is the relationship between sound waves and mediums?

Back

Sound waves require a medium (solid, liquid, or gas) to travel through. The speed of sound varies depending on the medium, with sound traveling fastest in solids.

Front

What happens to sound waves when they travel through wood?

Back

When sound waves travel through wood, they speed up, which can result in a higher frequency sound being heard.

Front

What is the product of photosynthesis?

Back

The main products of photosynthesis are glucose (a type of sugar) and oxygen.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as mechanical energy being converted to electrical energy in a wind turbine.

Front

What is the difference between kinetic and mechanical energy?

Back

Kinetic energy is the energy of motion, while mechanical energy is the sum of potential and kinetic energy in a system.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the survival of most living organisms, as it is used in cellular respiration.
